Answer to Question 1

ANS: B
Patients with severe infections should be treated while culture results are pending. If a patient has a severe infection or is at risk of serious sequelae if treatment is not begun immediately, it is not correct to wait for culture results before beginning treatment. Until a bacterial infection is ruled out, treating symptomatically is not indicated. Treating without obtaining cultures is not recommended.

Answer to Question 2

ANS: D
Antibiotics promote resistance by destroying sensitive organisms and eliminating the toxins they produce, which facilitates survival of resistant organisms. Antibiotics do not alter the genetic makeup of bacteria. The host cells are not affected. Antibiotics are not mutagenic.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
